Rail transit vibration damper

Abstract

The invention is suitable for the technical field of rail transit equipment, and provides a rail transit vibration damper. The vibration damper comprises a vibration damping seat and a rail, a mounting cavity is formed in the vibration damping seat, the rail is fixed on a sleeper, the rail transit vibration damper further comprises a vibration damping mechanism, and the vibration damping mechanism comprises a connecting box, a pushing assembly, a sliding part, a rotating assembly, a fixing part, a vibration damping part and a clamping part; and the pushing assembly comprises a connecting base and a pushing piece. According to the rail transit vibration damper, when a train runs on the rail, the wheels of the train make contact with the rail to generate vibration and pressure on the rail, part of the vibration and pressure of the rail are transmitted to the rail web of the rail, and the vibration and pressure borne by the rail web can be counteracted through the damping mechanism to achieve vibration reduction and supporting of the track, so the vibration reduction effect of the device is improved, the service life of the track is prolonged, and the economic cost of track traffic is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a rail transit vibration damping device. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the continuous development of my country's economy and technology, the construction of rail transit is gradually increasing. At the same time, with the increase of train speed and traffic density, its impact on the surrounding environment is becoming more and more serious. Among them, the noise caused by track vibration is the most important factor affecting the environment during train operation. When the train passes by, under the interaction between the wheel and the rail, the track and the wheel vibrate at the same time, radiate noise outward, and the...

Problems solved by technology

[0003] At present, in the field of rail transit, for the vibration reduction of the track, the damping material is directly laid on the non-working surface of the track or the restraint damping plate is bonded to realize the vibration reduction treatment of the track, and then the noise caused by the track vibration is controlled; However, this kind of material has limited damping effect on the track, and is easily damaged by external factors; and the vibration generated by the contact between the wheel and the track and the pressure of the train on the track will be transmitted to the rail waist of the track, due to the "work" of the track Word setting, the vibration and pressure on the rail waist will directly cause damage to the rail, reducing the service life of the rail
